A E S ITE A r phfih SINGLETREE- -CLEVIS.

SPECIFICATION forming part of Letters Patent No. 617,264, dated January 3, 1899.

Application filed March 15, 1898- To all whom, it may concern:

Be it known that LGILBERT THORsEN,a citizen of the United States, residing at Letcher, in the county of Sanborn and State of South Dakota, have invented certain new and useful Improvements in Singletree-0levises and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The special object of the invention is to dispense with old styles of clevis in which rings, hoops, loose pins, keys, or nuts were employed and to enable the single or double tree to be placed on top of the evener, so as to work freely from side to side without being caught in anything; also, to connect all the parts permanently together, so that none can be lost, mislaid, or become loose. For this purpose I provide a double lock which is very easily manipulated, but cannot be unlocked by accident.

The invention will first be described in connection with the drawings, and then pointed out in the claim.

Figure 1 of the drawings is a side elevation showing the pin-arms thrown back. Fig. 2 shows the clevis closed, and Fig. 3 is a detail View of the stop.

In the drawings,Arepresents the bodyof the clevis, with the fixed projection B, end slots 1) b, and cross-pins 22 b while 0 D represent hinged arms with pins ed at an angle there- Serial No. 673,896. (No model!) to and having shoulders 0 cl near their free ends. The arms 0 D have rear slots 0 d which enable them to slide on the cross-pins b b in order to free the pin-shoulders 0' cl from engagement with the body A.

E is a stop hinged on the pin 1) and. provided with a slot e, within which works the arm 0. When this stop is raised, as shown in Fig. l of the drawings, the arm 0 can be slid back on its cross-pin 12 so as to allow the pin 0 to be disengaged and taken out of the slot. This permits the arm D to be slid back on its hinge-pin b and to be taken out of its body-slot b.

It will be thus readily perceived that I get a double lock on my clevis, which makes it very secure, while the clevis can be opened or closed with great facility.

These clevises will be made of different sizes and perhaps slightly changed to suit particular vehicles, but without departing from the principle of my invention.

What I claim as new, and desire to protect by Letters Patent, is

A singletree-clevis having the body A with projection B, the slots 13 b and cross-pins b h in combination with the two hinged arms 0 D and hinged stop E, the arms being provided with the shouldered pins F, G, at an angle thereto, all constructed and arranged substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
